Help me chose a custom rifle action

[Awag1000]

I currently have a List to build a rifle on a Long Magnum action. the action I have chosen right now is a Curtis Helix however I find there are other action choices out there.
things I am looking for right now are;
Remington 700 footprint (ill be using a Manners PRS stock)
I love 60 degree bolt lift (this is a Must)
Easily User Serviceable. (parts availability is a big thing with me)
Good Customer service would be nice in case something critical breaks
Uses R700 Triggers.

what would you suggest I use? why?
Thank you for your time.

To me, nothing is more iconic than a ARC Mausingfield and a long action. That's what I plan on using if I ever build a 300 Norma.

The only thing that it doesn't have is your 60 degree throw.. none of their actions do. but when you watch videos about ARC action, he (Ted) talks about why he doesn't like 60 and how a longer bolt throw is easier to use as far as pressure goes.

I'm just a sucker for Mauser too. but ARC makes a couple of LA that you can look at.
